The TransportStructure( 'dst', 'src', 'p' ) command uses the permutation p to produce an isomorphic copy of the source magma src in the array dst, in such a way that the permutation p is then an isomorphism from src to dst.

A more convenient, but less efficient interface to this functionality is provided by the IsomorphicCopy command, which allocates storage for the resulting Cayley table automatically.
